LAWN-SPRINKLER.

Application filed January 5, 1915.

To all whom it may concern. Be it known that I, EARL V. CoULsToN, a

citizen of the United States, resident of Cleveland, county ofCuy'ahoga, and State of Ohio, have invented a new and useful Improvementin Lawn-Sprinklers, of which the following is a specification, theprinciple of the invention being herein explained and the best mode inwhich I have contemplated applying that principle, so as to distinguishit from other inventions.

My invention relates to lawn sprinklers, its object being to provide asprinkler which may be attached to a lawn hose in the usual manner,which will operate eliiciently and which may be manufactured at acomparatively low cost.

The said invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawing and the following description set forth in detailcertain. means embodying my invention, the disclosed means, however,constituting but one of various mechanical forms in which the principleof the invention may be applied.

In said annexed drawings :Figure 1 represents a plan of a sprinklerembodying my invention, showing a fragmentary portion of the end of ahose to which it is attached. Fig. 2 represents a vertical axial sectionof the parts shown in Fig. 1. Fig. 3 represents a front elevation andFig. 4 a side elevation.

The illustrated embodiment of my invention comprises a unitary structurehaving three main parts, a main or body portion 1 of general cylindricalform, an end wall 2, and lateral members 3. The main or body portion 1is provided with interior threads 4 by means of which the sprinkler maybe attached to the usual nipple 5 of an ordinary lawn hose. The end wall2 consists of three parts, a lower part 6, an upper part 7 and anintermediate part 8. The upper part 7 is substantially plane and alsosubstantially perpendicular to the main or body portion 1 and has aninterior flat surface 9. The interior surface of the lower part 6 isconcave and spherical in form and its upper end terminates substantiallyin a horizontal plane passing through the axis of the main or bodyportion 1. The upper end of the lower portion 6 and the lower end of theupper portion 7 of the outer wall are connected by the flat portion 8,as shown. The

Specification of Letters Patent.

Serial No. 5%. 1

middle ofthe upper portion 7 and intermediate or connection portion 8are pierced by a rectangular slot 12, as shown in Figs. 1, 2 and 3.

In using the above described device, it is attached in the usual mannerto the hose and water and into the sprinkler, from which it emergesthrough the slot 12. The. lower spherical surface 10 being substantiallyinclined to the axis of the sprinkler and hence inclined water, it willbe seen that the lower portion of the body of the water will bedeflected so as to pass upwardly through the lower part of the slot 12,as shown in dotted lines in Fig. 2. The upper portion of the body of thewater, however, passes straight through the upper part of the slot 12,with the result that two opposing and converging streams are formedwhich meet and cause a spatulate spreading of the water, as shown inFig. 1, whereby such water is distributed in an economical and eflicientmanner. The slot and the inner adjacent surface are so arranged that theplane of the spatulate body of water will be slightly and upwardlyinclined with reference to the horizontal, as shown in Fig. 2.

In order to position the device upon the ground, the main or bodyportion has secured thereto, two laterally extending and integral legs13, 13, Figs. 3 and 4, which rest upon the ground and hold the device ina position in which the major dimension of the slot 12 issubstantiallyperpendicular.

It will be seen from the above description that a very simple sprinkleris thus obtained, which may be made with all its parts integral witheach other and hence may be manufactured at a low cost.

Having fully described my invention, what I claim and desire to secureby Letters Patent is 1. As a new article of manufacture, a sprinklerhaving a cylindrical portion adapted to be connected with a hose, andhaving an end wall comprising a portion inclined with reference to theaxis of said cylindrical portion, a portion substantially perpendicularto said axis, and a portion joining said perpendicular and inclinedportions; said end wallbeing provided with an opening intersecting saidperpendicular and joining portions.

properly to the direction of entrance of the.

permitted to pass therethrough I 2. As a new article of manufacture, alawn sprinkler comprising a main or cylindrical portion adapted to beconnected with a hose; an end wall comprising three parts, a lower part,an upper part and an intermediate or connecting part; said upper andintermediate parts being provided with an interior surface of substantia1y spherical form.

v 3, As a new article of manufacture, a

sprinkler having a cylindrical portion adapted to be connectedwith ahose, and an end wall comprising a lower portion inclined with referencetothe axis of the cylindrical portion a portion substantiallyperpendicular and transverse with respect to j a slot passingtherethrough; ,"said lower part having EARL 'V. COULSTON.
